Rolling Copper Cold is a specialized piece of equipment designed to manufacture copper tubes by bending and forming flat copper sheets into cylindrical or coiled shapes. The Copper Rolling Mill Cold uses a combination of rollers and dies to apply pressure, forcing the copper material into the desired shape and ensuring a smooth, even surface. Rolled copper foil is made by repeatedly rolling a copper sheet.
copper ingot→ hot press tempering→ toughening→ plane to remove scale→ cold roll→ continuous toughening→ acid washing→ rolling→ degreasing and drying.
The raw foil of rolled copper foil is obtained in this way. The raw foil then receives roughening, heat-resisting layer treatment, and passivating treatment for the prevention of oxidation according to requirements.
